SILT-ACCUMULATOR.

Specification of Letters Patent.

Patented Aug. 30, 1921.

Application led March 25, 1921. Serial No. 455,521.

To all whom t may concern:

Be it known that I, HENRY F. KELLNER, a citizen of the United States, residing at Silver Lake, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Silt-Accumulators, of which the following is a specification.

This invention relates to an improvement in silt accumulators for use in forming deposits of silt in flowing waters and particularly for preventing erosion of the banks of streams, and has for one of its objects. to pro vide such a form that the silt which moves near the bed of a stream may be accumulated to advantage, the upper part of the accumulator having such'form that its resistance to the force of moving water will not cause any material displacement of the device in the bed of the stream. The invention also has for one of its objects tol provide a silt accumulator consisting of few and simple parts so that it may be conveniently and economically constructed.

In the accompanying drawing, Figure 1 shows a perspective view of the silt accumulator in operative position. Fig. 2 is a view of the silt accumulator in side elevation. Fig. 3 is a top plan view of the same. Fig. 4 is a perspective View showing connected silt accumulators in a stream.

Referring now to the drawing, the silt accumulator includes an approximately rectangular base consisting of elongated, horizontal, rigid members 5 connected at their ends by bands 6 or other suitable means, together with horizontal, rigid members or cross-strips 7 disposed diagonally with reference to members 5, a rigid standard 8 being connected with the cross-strips 7 at their intersection, a plurality of third rigid members or strips 9 being secured at their upper ends to the standard near the upper end thereof by bands l0, thelower ends of members 9 being secured by bands 6 to members 5 and 7 at or near the ends thereof.

As thus described an upright frame is provided of pyramidal form. Numerals 1l indicate strands which are connected at their upper ends with the standard, this connection preferably being midway between the ends thereof, the lower ends of the strands 11 being secured to the ends of members 7. and 9 at the intersection thereof. Numerals 12 indicate secondary strands which are also connected at their upper ends with the standard, midway between the ends of said standard, their lower ends being secured to the base of the silt accumulator, said connection being with the horizontal members 5, between the ends thereof or with the cross-strips outwardly from the band 13, the latter being used for securing the standard to the crossstrips at their intersecting parts.

In operation, for controlling or delecting a current of water to cause precipitation of silt, a plurality of accumulators :n are generally employed, their bases being connected by cables c and disposed near to each other, and connected with the shore by a cable o to partly obstruct a stream, anchors c being used so that the bases will be maintained flatwise upon the bed of the stream. On account of the pyramidal form provided, together with the arrangement of the strands ll and l2 which form a second permeable frame of pyramidal form above the base having its apex terminating midway between the base and apex of the frame provided by the base and members 9, the water will be deflected to advantage to cause accumulations 14 of silt in flowing water at the down-stream side of an accumulator. However, since the upper part of the device will cause only a slight resistance, comparatively, to flowing water, overturning of the accumulator is not likely to occur.

lVhile I have described the construction in detail, I do not wish to be understood as limiting myself to eXactness in this respect, and changes in form, size, proportion and minor details may be made as found to be of advantage, the scope of the invention being determined by its claims..

I claim:

1. In a silt accumulator, basel including rigid, elongated members connected at their ends and cross-stripsdisposed diagonally with reference to and connected with said rigid elongated members, a standard secured to the cross-strips at the intersecting parts thereof, rigid, elongated members connected at their lower ends with the base at the corners thereof and connected at their upper ends with the standard, and a plurality of strands connected with the rigid, elongated members of the base and connected with the standard midway bea rectangular tween the ends thereof.

2. In a siltA accumulator, a rectangular base including rigid, elongated members connected at their ends and rigid Vcrossstrips disposed diagonally with reference to and connected with said rigid, elongated members, a standard secured to the crossstrips at the intersecting parts thereof, rlglc,

elongated members connected at their lowerV ends with the base and secured at their upper ends to the standard, a plurality et strands cenne1;ted at one of their ends with the rigid7 elongated members of Jche base, and a. plurality or second strands connected with the cross-strips, said first named strands and second strands being connected with the standard between the ends thereof.

2?. En a silt accumulator, a hase including r'j'd crossstrips having their intersecting parts eennected, rigid supporting` members eennecting eafh 'terminal part of a crossstrip with the terminal part et an adjacent erossstrip, a id standard secured to the rigid cress-stris at the intersectinv parts thereof, supperting-mei'nhers connecting the standard near its upper terminal With the end portions of the crossetrips and a plurality ot strands connecting the standard, between its ends, with said base.

4f ln silt accumulator, a base including rigid cross-strips having connected intersecting parts, supperting-members connecting' each terminal )art of a cross-strip with the terminal part et" an adjacent cross-strip, a standard secured to the cross-strips at the intersecting 'parts thereof, supporting-members connecting the standard near its upper terminal With the end portions ot' the crossstrips, and a plurality of strands connecting said base with` the standard. y

In testimony whereof, l have aiixed my signature in presence of two Witnesses.
